摘要

•Machining process plays a notable role in the fatigue properties of the printed CrFeCoNi alloy.•Annealing decreases the yield strength of the printed CrFeCoNi alloy.•Heat treatment does not affect the fatigue life of printed CrFeCoNi alloy in the HCF regime.•Recrystallization process of the printed CrFeCoNi alloy occurs at 800°C.•Secondary phases are observed in the printed CrFeCoNi alloy after annealing at 800°C.
